Ubuntu 12.04 LTS / 12.10 : keystone vulnerabilities (USN-1641-1)

medium Nessus Plugin ID 63093

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Vijaya Erukala discovered that Keystone did not properly invalidate EC2-style credentials such that if credentials were removed from a tenant, an authenticated and authorized user using those credentials may still be allowed access beyond the account owner's expectations.
(CVE-2012-5571)

It was discovered that Keystone did not properly implement token expiration. A remote attacker could use this to continue to access an account that is disabled or has a changed password. This issue was previously fixed as CVE-2012-3426 but was reintroduced in Ubuntu 12.10. (CVE-2012-5563).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-keystone package.
